Server Mediator for Cross-Cloud Printing State Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing cloud printing systems, the first cloud printing service system is not notified of the state related to printing performed by the second cloud printing service system, leading to a lack of awareness for users about the printing state via the first system.
Innovation Solution
A server is connected to both the first and second printing service systems, featuring an acquisition unit to obtain the job state from the second service system and a transmission unit to relay this state to the first service system, ensuring that the job state is communicated and made available to users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cloud printing management service system associates a virtual printer with a printing device across different cloud printing service systems, then printing functionality is enabled between systems, but the first cloud printing service system cannot receive printing state notifications from the second system
Solution Approach 1:
The patent introduces a server as an intermediary component that receives printing state information from the second cloud printing service system and forwards it to the first cloud printing service system. This mediator resolves the information isolation between systems while maintaining the existing virtual printer association mechanism, allowing state information to flow across system boundaries without disrupting the core printing functionality.
2Loss of information
If printing state information is transmitted between cloud printing service systems, then user awareness of printing state is improved, but system complexity increases
Solution Approach 1:
By positioning the server as a dedicated intermediary, the patent centralizes the information transmission logic in a single component rather than distributing complexity across multiple systems. The server handles all state information forwarding between the first and second cloud printing service systems, simplifying the overall architecture while ensuring reliable information delivery.
Solution Approach 2:
The patent segments the information transmission function from the core printing service systems by introducing a separate server component. This segmentation allows each cloud printing service system to maintain its independence while the dedicated server handles the cross-system communication, reducing the complexity burden on the primary systems.

AI summary
A server is connected to a first printing service system and a second printing service system that is connected to an image processing device. The server includes an acquisition unit configured to acquire a job state of printing processing executed by the image processing device from the second printing service system, and a transmission unit configured to transmit the job state to the first printing service system when the job state is acquired from the second printing service system.
